 - [Phase 19]: Router icon for RouterOS, Network icon for SNMP -- follows lucide semantics
 - [Phase 19]: device_type defaults to routeros via nullish coalescing for backward compat
 - [Phase 19]: SNMP devices get their own layout branch (not stripped RouterOS) for clean first-class experience
+- [Phase 20]: MIB_PARSER_PATH config with /app/tod-mib-parser default; shutil.which fallback for dev
+- [Phase 20]: Test-profile tests connectivity only (existing discovery probe), not full per-OID walk
+- [Phase 20]: AppendPath instead of SetPath to preserve gosmi default IETF MIB search paths
+- [Phase 20]: Virtualized flat list for OID tree (no tree library, reuses tanstack/react-virtual)
+- [Phase 20]: Three fixed poll groups (fast/standard/slow) with click-to-activate paradigm
+- [Phase 20]: Test panel starts collapsed since OID editing is primary workflow
